Our school has students who speak over 40 different languages and dialects at home. Often there is an older student in the school that speaks the language and can help with some simple written translations. The district or ELL department in your district may have translators available for conferences and IEP meetings. Send pictures home of what their child is doing in class to help them feel connected. Making your newsletters as visual as possible helps. Think putting a calendar with dates marked and and a visual of what is happening that day on it. We hosted an International Night where parents could come set up a booth with food, pictures, music, crafts, etc. reflecting their culture. It was amazing to see families participate who we had never had take part in school functions before. The key was to make them feel welcome in a way that they felt they could give back.
